Abstract:
An experiment was conducted with thirty genotypes of grain cowpea during 2019-21 at the Department of Plant Breeding and Genetics, College of Agriculture, Vellayani. Observations were recorded on sixteen characters viz., number of days for germination, germination percentage, days to first flowering, days to 50% flowering, plant height (cm), number of primary branches plant-1, number of secondary branches plant-1, pod length (cm), number of pods plant-1, number of seeds pod-1, days to maturity, dry pod weight plant-1 (g), 100-seed weight (g), seed yield plant-1 (g), crude protein content (%) and crude fiber content (%). A wide range of variation exhibited for yield and yield attributing traits among the genotypes under study. The analysis of variance revealed significant variation among the genotypes for all the characters studied. PCV and GCV values were highest for seed yield per plant (g). High GCV values with reasonably high PCV values were seen for dry pod weight per plant, number of secondary branches per plant, plant height, germination percentage, 100 seed weight, and number of pods per plant. Heritability was high for all traits except number of pods per plant and number of primary branches per plant, and genetic gain was high for all traits except number of primary branches per plant, crude protein content, crude fibre content, and days to maturity.
